LAMP HOLDER.

Application filed March 2,

' be illuminated.

A further object of the invention is to furnish a lamp holder which is strong and durable, exceedingly simple in construction,

I highly efficient and convenient in practical use, and which may be cheaply manufactured.

With the above and other objects in view, the invention comprises a novel combination and arrangement of parts to be hereinafter described and claimed, and in order 'that the. same may be better understood,

reference is had to the accompanying drawing, forming a part of this specification, and wherein the preferred embodiment of the invention is disclosed.

In the'drawing, Figure 1 is a perspective view showing I my device with a lamp in place;

Fig. 2 is atop plan view with the lamp removed; Fig. 3 is a bottom Fig. 2, and I q Fig. 4c'is a transverse section through Fig. 2. a v -Referring specifically to the drawing, wherein like characters of reference 'desig plan View similar to nate like parts throughout the several views, 51

numerals 5 and v6 denote sheet metal clamping strips having intermediate their ends,

diametrically opposite pairs of fingers 7 ,the' free endsof which are bent inwardly and backwardly through an, angle of 180 to form substantially loop like members, the purpose of which will be presently described-- The strips 5 and 6 are formed at one end with arcuate clamping'portions 8 between which the socket 9 of an electric lamp 10 is adaptedto be held.

The clamping strips 5 and-6 are'pivotally connected and normally held in clamping position with their dished ends in contact through the medium of a coil spring 11 which is securelyand detachably -held in 1922. Serial No. 540,557.

positionv between the strips 5 and 6 by means of the, fingers 7 as clearly. shown in the drawing. By this construction it will be evident that tie spring 11 performs a dual function in that it not only serves to maintain the strips 5 and 6 normally in clamping position but also serves as a bearing or pivot for the strips.

Atthe end opposite its dished portion 8, and 'for a substantial distance toward said dished portion, the clamping strip 5 is formed with a lateral inturned flange 12 which carries intermediate-its ends a pair of diametrically opposite fingers 13 which are bent downwardly and inwardly with their free ends in alinement to forma loop-like retainer to which there is pivotally secured a clamping-strip 14 by means of a coil spring 15 which engages similar fingers'lfi carried by the clamping strip'll. It will be evident that this spring 15 alsoperforms a dual function as previously described in connection with the spring 11 and that it may be readily detached if desired; The strip 14 will be normally held in plamping position to effectually grip a limb of a tree or other support between its clamping end and the flange 12 and maintain the clamping strips 5 and 6 in vertical position. The flange 12 also serves as a rest for the clamping strip 6.

7 Numeral 17 designates an annular, aperture'd reflector which may be placed above the circumferential opening formed by the arcuate portions 8 when in clamping position, and through the aperture of which the socket 9 of the electric lamp maybe injserted, as clearly ,shown in Fig. 1. By this arrangement it will be seen that the reflector will be securely held against displacement and may be readily positioned or removed as desired.

From the foregoing description, taken in connection with the accompanying draw-- 'ing, the operation of the device will be apparent and further elaboration is thought i to be unnecessary. While I have described and shown the preferred embodiment of my invention, it will be uriderstood that I do notlimit myself thereto, since various changes and modifications may be made in I the same within the spirit and scope of the invention as defined in the appendedclaims.

I claim:

pair of clamping members having opposed 1. An electric lamp holder comprising a b g I lamp engaging portions at one end thereof, a pivotal and-yieldable connection between said clamping members for yieldingly ho-ld ing said lamp engaging portions in engaging position, a laterally extending flange carried by one of said clamping members-'- and extending transversely of and beyond one longitudinal edge of the other clamping member forming a support therefor, and clamping means associated with the outer face or" said flange for securing said holder to a support.

2. An electric lamp holder comprising aw pair of clamping/members having opposed Lemme member, and a clamping member yieldably and detachably carried by said flange for securing said holder to a support. a

3. An electric lamp holder comprising a pair of separably connected clamping members having opposed lamp engaging portions at one end thereof, a pair of'fingers carried by the longitudinal edges of each of said clamping members said fingers being inturned, a coil spring engaging the fingers of each of said clamping members forming a pivotal and yieldable connection between said clamping members for separab'ly connecting and yieldably holding said lampfengaging portions in engaging posltion, and a hinge carried by one of said clamping members forxsecuring said holder to a support., in testimony whereof I ture.
